US Patent Office found the patent invalid based on prior art a year ago, 
and it already expired anyway.

That gnu.org page on gif is pretty old. The GIF patents expired a few 
years ago IIRC.

It seems reasonable to support PNG anyway as its a standard format, so 
let's see how small gimp will let me squeeze them down in PNG format.
